Last month, my client Kelvin finally found a property he liked in Kowloon Bay—a two-bedroom unit, relatively new, with an open view, and most importantly, the price per square foot was 8% lower than similar units in the area. But just as he was about to place an order, the real estate agent suddenly reminded him, 'There's a 5G base station on the rooftop upstairs; do you mind?' Kelvin hesitated on the spot, with words like 'radiation' and 'health risks' flashing through his mind, but at the same time, he also thought, 'The internet speed should be very fast.' This contradiction put him in a dilemma.
This scene is something that many prospective homebuyers have probably encountered. With the full rollout of 5G networks in Hong Kong, the number of base stations has surged, and these 'mysterious installations' can now be seen near many residential developments. How exactly do 5G base stations impact the property market? Are radiation concerns a real threat, or just an overblown fear? Today, we will use scientific data and practical experience to break down this emerging issue in the Hong Kong property market for everyone.
:::tip Expert tips According to data from the Communications Authority, as of 2024, Hong Kong has over 18,000 5G base stations in operation, with a coverage rate of over 90%. This means that there is a base station near almost every residential estate. :::
The Truth About 5G Base Station Radiation: Scientific Data vs. Popular Rumors
What is 'Non-Ionizing Radiation'? Completely Different from X-Rays
Many people, when they hear 'radiation,' immediately think of nuclear power plants or hospital X-ray machines. However, 5G base stations actually emit 'non-ionizing radiation,' which is a type of electromagnetic wave. This type of radiation has extremely low energy and is insufficient to damage the DNA structure of human cells, making it fundamentally different from 'ionizing radiation' (such as X-rays and gamma rays) that can cause cancer.
According to studies by the World Health Organization (WHO) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP), the radiation levels of 5G base stations are far below international safety standards. The Communications Authority of Hong Kong also regularly monitors base stations throughout the city to ensure that radiation levels comply with safety regulations.
:::highlight Key data Hong Kong law stipulates that the radiation level of base stations must not exceed 50% of the ICNIRP standard. Actual measurement data show that even when standing directly under a base station, the radiation level is only 1-5% of the safety standard, far lower than the amount of radiation received when using a mobile phone. :::
5G Base Stations vs Mobile Phone Radiation: Which Is More 'Dangerous'?
Here is a counterintuitive fact: the radiation from the phone you hold to your ear every day is actually higher than that from a base station. This is because the phone actively emits signals to connect to the base station, while the base station only passively receives and forwards signals. The closer you are, the lower the transmission power the phone needs; conversely, when you are in a remote area or a place with poor signal, the phone will automatically increase its transmission power, and the radiation will increase accordingly.
In other words, if you are really concerned about radiation, you should pay more attention to your mobile phone usage habits (such as long calls or placing it by your pillow while sleeping) rather than the base stations near your building. In fact, the denser the base stations, the lower the transmission power of each one, and the smaller the impact on the human body.
Hong Kong Housing Market Situation: The Real Impact of Base Stations on Property Prices
From the perspective of real estate investment, the impact of 5G base stations on property prices shows a 'polarized' phenomenon:
Negative Impacts (Primarily Psychological Factors):
- Some buyers avoid units near base stations due to 'radiation fear,' resulting in larger negotiation room for these units.
- Rooftop base stations may affect the view or privacy of top-floor units.
- In certain estates, owners have launched actions against base stations, causing community disputes.
Positive Impact (Practical Value):
- Extremely fast internet speed, suitable for users working from home (WFH) or streaming entertainment
- 5G coverage becomes an infrastructure advantage for future trends like "smart homes" and "remote healthcare"
- Young buyers (especially those in the tech industry) actually consider it a plus
:::success Insider's observation I once handled a case in a housing estate in Tseung Kwan O, involving two units facing the same direction—one was a top-floor unit directly below a base station, and the other was a mid-floor unit. The top-floor unit eventually sold at 5% below the market price, but the buyer was an IT professional who admitted that a 'faster internet speed than others' was the main consideration. This reflects that the market's perception of base stations is becoming divided. :::
Practical Guide to Choosing a Property: How to Evaluate the Investment Value of a 'Base Station Property'
Three Major Evaluation Indicators: Location, Type, Distance
Not all 'cell towers' are worth avoiding; the key lies in the following three points:
1. Base Station Location
- Rooftop Base Station: Has the greatest impact, especially for top-floor units which may face view or noise issues (operation noise from the cooling system)
- Exterior Wall Base Station: Has a smaller impact, but attention should be paid if it faces unit windows directly
- Independent Tower: Usually located on the outskirts of the estate, with the least impact on residents
2. Base Station Types
- Macro Cell: Wide coverage, higher power, but fewer in number
- Small Cell: Small coverage, very low power, will become mainstream in the future
3. Distance and Floors
- Beyond 10 meters from the base station, radiation levels have dropped to background levels
- Units on low to middle floors are minimally affected by the base station, and can instead enjoy high-quality internet speeds
:::warning Guide to Avoiding Pitfalls If the unit you are considering is located directly below the rooftop base station (i.e., the top floor), it is recommended to pay attention during an on-site inspection:
- Does the base station equipment have noticeable noise (especially at night)?
- Is there a passage on the rooftop for maintenance personnel to enter and exit regularly?
- Whether the base station obstructs the unit's view or rights to use the rooftop

Negotiation Strategies: How to Turn 'Psychological Discounts' into an Investment Advantage
For savvy investors, 'base station plots' are actually a good opportunity for bargaining. Here are some practical strategies:
Strategy 1: Targeting the Landlord's Psychology
- If the landlord has concerns about the base station, you can use this as a reason to request a 3-5% discount
- Emphasize that "the market generally has reservations about base stations" to increase bargaining leverage
Strategy 2: Target Specific Buyer Groups
- Young professionals (IT, finance, creative industries) have high demand for internet speed
- The WFH crowd sees stable and high-speed internet as a necessity
- These buyers are actually willing to pay a premium for the '5G advantage'
Strategy Three: Long-term Holding Mindset
- With the widespread adoption of 5G, the market's acceptance of base stations will gradually increase
- In the future development of "smart cities," 5G coverage will become a standard part of infrastructure
- The current "psychological discount" may disappear in 5-10 years
:::tip Experts recommend If you don't mind base stations yourself, and even consider network speed an advantage, then a 'base station property' is definitely a great choice to get on the property ladder. I suggest focusing on new development areas such as Kowloon East, Tseung Kwan O, and Tung Chung. These areas have well-established 5G infrastructure, but the market still has discount potential due to 'radiation fears'. :::
Mortgage and Insurance Considerations: Will the Bank 'Turn a Blind Eye'?
A reader once asked: 'Will the presence of a base station affect mortgage approval or valuation?' Based on my experience, the answer is 'almost never.'
Mortgage Approval:
- Banks mainly consider the age of the building, location, and property price; the base station is not a factor in approval.
- Unless the base station causes obvious structural issues (extremely rare), it does not affect the mortgage.
Valuation Impact:
- The surveyor firm's valuation mainly references transactions in the same area; the impact of base stations is already reflected in the market price.
- If the "base station properties" in the area generally have a discount, the valuation will be adjusted accordingly.
Fire and Home Insurance:
- Insurance companies will not refuse coverage or increase premiums because of base stations
- Base stations are legal public facilities and do not constitute an insurance risk
Future Trends: How 5G Base Stations Will Change Hong Kong's Property Market
The Era of Smart Homes: Internet Speed Becomes a New Selling Point
With the popularization of smart homes, a stable and high-speed network connection has become an 'invisible amenity' in modern residences. Imagine: smart door locks, voice assistants, remote monitoring, automatic curtains, smart air conditioners... all these devices rely entirely on a stable network to function. Units near 5G base stations naturally have this advantage.
According to research by the Hong Kong Science Park, it is expected that by 2026, over 60% of new residential buildings will be equipped with smart home systems. By then, '5G coverage' will change from 'optional' to 'essential,' just like broadband has become today.
Normalization of Remote Work: The New Homeownership Standards for WFH Workers
After the pandemic, remote work (WFH) has become the norm in many industries. For workers who need frequent video meetings, upload large files, or use cloud systems, slow internet speed equals 'low work efficiency.' I have a client who is a designer, and he clearly stated, 'I would rather have a smaller apartment as long as the internet speed is fast,' and ultimately chose a unit near a base station in Tseung Kwan O.
The emergence of this type of buyer is changing the market's perception of 'base station properties.' In the future, '5G advantages' may become a selling point of a property, rather than a drawback.
:::highlight Market Observation According to Midland Property data, in 2023, in areas with complete 5G coverage, such as Tseung Kwan O and Kowloon Bay, the increase in property prices outperformed the Hong Kong average by 2-3 percentage points. Although it cannot be directly proven to be related to base stations, it reflects that young buyers are paying more attention to "technology support". :::
Government Policies and Infrastructure Planning: Base Stations Will Become More 'Invisible'
In recent years, the Hong Kong government has actively promoted the 'Smart City' blueprint, with 5G infrastructure being a core component. To reduce public concerns, the Communications Authority has required telecom operators to adopt more aesthetically pleasing and lower-power 'microcell' designs, even disguising base stations as streetlights, billboards, and other urban facilities.
This means that future base stations will be more 'invisible,' and their psychological impact on the real estate market will be further reduced. Buyers who currently still experience 'radiation panic' may find in 5-10 years that the 'base station properties' they avoided at the time were actually missed opportunities to get in on the market.
Summary: Rational Analysis, Seizing Market Mismatch Opportunities
Returning to the beginning of the article with Kelvin's story, he ultimately decided to buy that 'base station unit.' The reason was simple: he did his homework, understood that the radiation risk was minimal, and the advantage in internet speed was very helpful for his work-from-home job. More importantly, he successfully negotiated a 5% discount, effectively making the purchase 'cheaper than renting,' which would definitely be worthwhile in the long term.
For first-time homebuyers and investors in the Hong Kong property market, the '5G base station' issue is a typical example of a 'market mispricing' opportunity: some buyers avoid it due to irrational fear, but the actual risk is very low, and it can even bring additional value. As long as you are willing to do your homework and analyze rationally, you can seize opportunities when others are fearful.
:::success Review of the three main points
- Radiation Issue: 5G base stations are non-ionizing radiation, with safety levels far below international standards, and the actual risk is lower than that of mobile phones
- Impact on Property Prices: At this stage, there is a 'psychological discount', but as market awareness increases, the discount margin will gradually narrow.
- Investment Strategy: For specific buyer groups such as the WFH crowd and technology industry professionals, 'base station locations' are actually a selling point.

Remember, the most important thing in real estate investment is 'independent thinking.' When the market experiences irrational panic, it is often a good time for savvy investors to enter. The topic of 5G base stations is exactly a touchstone to test whether you have 'contrarian thinking.'
